From what I understand during peeking into the Discord every now and then, the wallet on hive.blog is not yet active. However, it is on peakd.com which is the Hive equivalent of SteemPeak.

I don't think all wallet features are active yet. For example: I don't want to risk changing my passwords for a few more days until things have settled, nor do I want to risk converting HBD to HIVE yet.

But it's fine for claiming rewards and seeing your wallet intact.
